 Only frey, mcclain, cindex, sihouette and dunn can be computed. To compute the other indices, data matrix is needed 

Dendrogram

Branches are colored according to the groups obtained by maximizing the silhouette width.

Tables Centroids & Mediods

Sites ordered according to their clusters delineated by hierarchical cluster analysis (Wards method) and according to their squared sum of differences to the centroid.

Sites closest to the centroid and mediods for each cluster.

Clusters & z-standardized values of environmental parameters

Numbers indicate each delineated cluster. Values for each variable are z-standardised (Stand_value), i.e. they can be interpreted in terms of differences in standard deviations from the mean. Colored sites are those sites that have the overall smallest sum of squared differences to the centroid.
